Fig. 3.

Trypsin releasable peptides of apolipoprotein B-100. The size of the markers reflect LC-MS/MS signal area vs. concentration regression slopes. The markers are colored by number of loop inducing (P + G) residues. The shown peptides exclude sequences containing methionine, passed linear response criteria across a dilution series (R2 ≥ 0.9), and contained between 7 and 16 residues.
